ANALYSIS

Spatial analysis using leaflet

# URL's below explain how to use functions and arguments in leaflet. It also contains info which notes that the radius of a circle is in meters. Therefore, 1.5 miles converts to 2400 meters.
# https://rstudio.github.io/leaflet/shapes.html
# https://github.com/Robinlovelace/Creating-maps-in-R/blob/master/intro-spatial.Rmd

# Creating a buffer zone, 1.5 miles from every NPO
# I followed the info from this site and tried to apply it to the analysis
